Notes to condensed consolidated financial statements (unaudited)

1.    Basis of Presentation and Responsibility for Interim Financial Statements

The accompanying unaudited condensed consolidated financial statements of Pentair plc and its subsidiaries (“we,” “us,” “our,” “Pentair,” or the “Company”) have been prepared following the requirements of the U.S. Securities and Exchange Commission (“SEC”) for interim reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by accounting principles generally accepted in the United States of America (“GAAP”) can be condensed or omitted.

We are responsible for the unaudited condensed consolidated financial statements included in this document. The financial statements include all normal recurring adjustments that are considered necessary for the fair presentation of our financial position and operating results. As these are condensed financial statements, one should also read our consolidated financial statements and notes thereto, which are included in our Annual Report on Form 10-K for the year ended December 31, 2020.

Revenues, expenses, cash flows, assets and liabilities can and do vary during each quarter of the year. Therefore, the results and trends in these interim financial statements may not be indicative of those for a full year.

In March 2020, the World Health Organization declared the novel coronavirus 2019 (“COVID-19”) a global pandemic. The COVID-19 pandemic has had and may continue to have an unfavorable impact on certain parts of our business. The broader implications of the COVID-19 pandemic on our business, financial condition and results of operations remain uncertain and will depend on certain developments, including the duration and severity of the COVID-19 pandemic, the impact of virus variants, the rate of vaccinations, the COVID-19 pandemic’s impact on our customers and suppliers and the range of governmental and community reactions to the pandemic. We may continue to experience reduced customer demand in certain parts of our business or constrained supply that could materially and adversely impact our business, financial condition, results of operations, liquidity and cash flows in future periods.

Our fiscal year ends on December 31. We report our interim quarterly periods on a calendar quarter basis.

2.     Revenue

We disaggregate our revenue from contracts with customers by segment, geographic location and vertical, as we believe these best depict how the nature, amount, timing and uncertainty of our revenue and cash flows are affected by economic factors. Refer to Note 15 for revenue disaggregated by segment.

Geographic net sales information, based on geographic destination of the sale, was as follows:

	Three months ended				Six months ended
In millions	June 30, 2021		June 30, 2020		June 30, 2021		June 30, 2020
U.S.	$	639.1	$	482.7	$	1,225.7	$	946.7
Western Europe	120.7		84.9		236.0		188.7
Developing (1)	120.5		100.4		225.9		194.9
Other Developed (2)	60.8		45.3		119.4		93.0
Consolidated net sales	$	941.1	$	713.3	$	1,807.0	$	1,423.3
(1) Developing includes China, Eastern Europe, Latin America, the Middle East and Southeast Asia.
(2) Other Developed includes Australia, Canada and Japan.

Vertical net sales information was as follows:

	Three months ended				Six months ended
In millions	June 30, 2021		June 30, 2020		June 30, 2021		June 30, 2020
Residential	$	599.5	$	439.7	$	1,171.2	$	855.5
Commercial	173.2		124.4		310.8		265.8
Industrial	168.4		149.2		325.0		302.0
Consolidated net sales	$	941.1	$	713.3	$	1,807.0	$	1,423.3

Performance obligations

On June 30, 2021, we had $83.3 million of remaining performance obligations on contracts with an original expected duration of one year or more. We expect to recognize the majority of our remaining performance obligations on these contracts within the next 12 to 18 months.

Contract assets and liabilities

Contract assets and liabilities consisted of the following:

In millions	June 30, 2021		December 31, 2020		$ Change		% Change
Contract assets	$	52.3	$	50.1	$	2.2	4.4	%
Contract liabilities	35.7		27.5		8.2		29.8	%
Net contract assets	$	16.6	$	22.6	$	(6.0)	(26.5)	%

The $6.0 million decrease in net contract assets from December 31, 2020 to June 30, 2021 was primarily the result of timing of milestone payments and impact of foreign currency fluctuations. Approximately 65% of our contract liabilities at December 31, 2020 were recognized in revenue in the first half of 2021. There were no impairment losses recognized on our contract assets for the three months ended June 30, 2021.

3.Acquisitions

On May 19, 2021, as part of our Consumer Solutions reporting segment, we completed the acquisition of Ken’s Beverage, Inc. for $82.8 million in cash, net of cash acquired. The excess of purchase price over tangible net assets acquired has been preliminarily allocated to goodwill in the amount of $29.3 million, all of which is expected to be deductible for income tax purposes. Identifiable intangible assets acquired consisted of $38.0 million of definite-lived customer relationships with an estimated useful life of 22 years.

In 2020, our Consumer Solutions reporting segment completed acquisitions with purchase prices totaling $58.0 million in cash, net of cash acquired.

The pro forma impact of these acquisitions is not material.

4.Share Plans

Total share-based compensation expense for the three and six months ended June 30, 2021 and 2020 was as follows:

	Three months ended				Six months ended
In millions	June 30, 2021		June 30, 2020		June 30, 2021		June 30, 2020
Restricted stock units	$	3.6	$	3.1	$	7.0	$	6.3
Stock options	0.9		0.6		1.8		1.6
Performance share units	6.5		0.5		7.8		2.5
Total share-based compensation expense	$	11.0	$	4.2	$	16.6	$	10.4

In the first quarter of 2021, we issued our annual share-based compensation grants under the Pentair plc 2020 Share and Incentive Plan to eligible employees. The total number of awards issued was approximately 0.7 million, of which 0.3 million were restricted stock units (“RSUs”), 0.3 million were stock options and 0.1 million were performance share units (“PSUs”). The weighted-average grant date fair value of the RSUs, stock options and PSUs issued was $55.42, $12.88, and $52.57, respectively.

Pentair plc and Subsidiaries

Notes to condensed consolidated financial statements (unaudited)

We estimated the fair value of each stock option award issued in the annual share-based compensation grant using a Black-Scholes option pricing model, modified for dividends and using the following assumptions:

	2021 Annual Grant
Risk-free interest rate	0.37	%
Expected dividend yield	1.56	%
Expected share price volatility	29.60	%
Expected term (years)	6.5

These estimates require us to make assumptions based on historical results, observance of trends in our share price, changes in option exercise behavior, future expectations and other relevant factors. If other assumptions had been used, share-based compensation expense, as calculated and recorded under the accounting guidance, could have been affected. We based the expected life assumption on historical experience as well as the terms and vesting periods of the options granted. For purposes of determining expected share price volatility, we considered a rolling average of historical volatility measured over a period approximately equal to the expected option term. The risk-free interest rate for periods that coincide with the expected life of the options is based on the United States (“U.S.”) Treasury Department yield curve in effect at the time of grant.

5.Restructuring and Transformation Program

During the second quarter of 2021, we launched and committed resources to a program designed to accelerate growth and drive margin expansion through transformation of our business model to drive operational excellence, reduce complexity and streamline our processes (the “Transformation Program”). The Transformation Program is structured in multiple phases and is expected to empower us to work more efficiently and optimize our business to better serve our customers while meeting our financial objectives.

During the six months ended June 30, 2021 and the year ended December 31, 2020, we initiated and continued execution of actions aimed at reducing our fixed cost structure and realigning our business associated with restructuring and the Transformation Program, including the reduction in headcount of approximately 50 and 175 employees, respectively.

Restructuring and transformation-related costs within Selling, general and administrative expenses in the Condensed Consolidated Statements of Operations and Comprehensive Income included the following: 

	Three months ended				Six months ended
In millions	June 30, 2021		June 30, 2020		June 30, 2021		June 30, 2020
Severance and related costs	$	4.2	$	1.1	$	5.1	$	3.8
Transformation and other costs	1.9		—		2.1		—
Total restructuring and transformation costs	$	6.1	$	1.1	$	7.2	$	3.8

Transformation and other costs primarily consist of professional services, project management and related costs, infrastructure charges to vacate facilities and consolidate operations, and asset impairment and various contract termination costs.

Restructuring and transformation costs by reportable segment were as follows:

	Three months ended				Six months ended
In millions	June 30, 2021		June 30, 2020		June 30, 2021		June 30, 2020
Consumer Solutions	$	0.2	$	1.4	$	0.7	$	2.0

7.Accounts Receivable

All trade receivables are reported on our Condensed Consolidated Balance Sheets at the outstanding principal amount adjusted for any allowance for credit losses and write-offs, net of recoveries. We record an allowance for credit losses, reducing our receivables balance to an amount we estimate is collectible from our customers. Estimates used in determining the allowance for credit losses are based on current trends, aging of accounts receivable, periodic credit evaluations of our customers’ financial condition, and historical collection experience as well as reasonable and supportable forecasts of future economic conditions. Write-offs are recorded at the time all collection efforts have been exhausted. We generally do not require collateral. We review our allowance for credit losses on a quarterly basis.

(1) The bad debt benefit for the year-ended December 31, 2020 includes the positive impact related to the adoption of ASU No. 2016-13     “Financial Instruments-Credit Losses.”
(2) Other amounts are primarily the effects of changes in currency translation and the impact of allowance for credits.

Total debt			$	716.6	$	839.6
(1) Senior notes are guaranteed as to payment by Pentair plc.

Pentair, Pentair Finance S.à r.l (“PFSA“) and Pentair, Inc. are parties to a credit agreement (the “Senior Credit Facility”), with Pentair as guarantor and PFSA and Pentair, Inc. as borrowers, providing for a $900.0 million senior unsecured revolving credit facility. The Senior Credit Facility has a maturity date of April 25, 2023. Borrowings under the Senior Credit Facility bear interest at a rate equal to an adjusted base rate or the London Interbank Offered Rate, plus, in each case, an applicable margin. The applicable margin is based on, at PFSA’s election, Pentair’s leverage level or PFSA’s public credit rating.

The Senior Credit Facility provides for the extension of term loans in an aggregate amount of $200.0 million (the “Term Loans”). We have utilized the term loan extension since December 2019. The Term Loans are in addition to the revolving credit facility commitment. In addition, PFSA has the option to further increase the Senior Credit Facility in an aggregate amount of up to $300.0 million, through a combination of increases to the total commitment amount of the revolving credit facility and/or one or more tranches of term loans in addition to the Term Loans, subject to customary conditions, including the commitment of the participating lenders.

PFSA is authorized to sell short-term commercial paper notes to the extent availability exists under the Senior Credit Facility. PFSA uses the Senior Credit Facility as back-up liquidity to support 100% of commercial paper outstanding. PFSA had no commercial paper outstanding as of June 30, 2021 and December 31, 2020.

In 2020, the commercial paper market began to experience high levels of volatility due to uncertainty related to the COVID-19 pandemic. The volatility impacted both market access to and pricing of commercial paper. As a cost mitigation action, we withdrew our credit ratings to access the commercial paper market and continued to use the revolving credit facility, along with cash generated from operations, to fund our general operations. As of June 30, 2021, total availability under the Senior Credit Facility was $883.9 million.

Our debt agreements contain various financial covenants, but the most restrictive covenants are contained in the Senior Credit Facility. The Senior Credit Facility contains covenants requiring us not to permit (i) the ratio of our consolidated debt (net of our consolidated unrestricted cash in excess of $5.0 million but not to exceed $250.0 million) to our consolidated net income (excluding, among other things, non-cash gains and losses) before interest, taxes, depreciation, amortization and non-cash share-based compensation expense (“EBITDA”) on the last day of any period of four consecutive fiscal quarters to exceed 3.75 to 1.00 (the “Leverage Ratio”) and (ii) the ratio of our EBITDA to our consolidated interest expense, for the same period to be less than 3.00 to 1.00 as of the end of each fiscal quarter. For purposes of the Leverage Ratio, the Senior Credit Facility provides for the calculation of EBITDA giving pro forma effect to certain acquisitions, divestitures and liquidations during the period to which such calculation relates.

In addition to the Senior Credit Facility, we have various other credit facilities with an aggregate availability of $21.4 million, of which there were no outstanding borrowings at June 30, 2021. Borrowings under these credit facilities bear interest at variable rates.

We have no fixed rate senior notes maturing in the next twelve months.

11.Derivatives and Financial Instruments

Derivative financial instruments

We are exposed to market risk related to changes in foreign currency exchange rates. To manage the volatility related to this exposure, we periodically enter into a variety of derivative financial instruments. Our objective is to reduce, where it is deemed appropriate to do so, fluctuations in earnings and cash flows associated with changes in foreign currency exchange rates. The derivative contracts contain credit risk to the extent that our bank counterparties may be unable to meet the terms of the agreements. The amount of such credit risk is generally limited to the unrealized gains, if any, in such contracts. Such risk is minimized by limiting those counterparties to major financial institutions of high credit quality.

Foreign currency contracts

We conduct business in various locations throughout the world and are subject to market risk due to changes in the value of foreign currencies in relation to our reporting currency, the U.S. dollar. We manage our economic and transaction exposure to certain market-based risks through the use of foreign currency derivative financial instruments. Our objective in holding these derivatives is to reduce the volatility of net earnings and cash flows associated with changes in foreign currency exchange rates. The majority of our foreign currency contracts have an original maturity date of less than one year.

At June 30, 2021 and December 31, 2020, we had outstanding foreign currency derivative contracts with gross notional U.S. dollar equivalent amounts of $10.6 million and $12.4 million, respectively. The impact of these contracts on the Condensed Consolidated Statements of Operations and Comprehensive Income was not material for any period presented.

Cross Currency Swaps

At June 30, 2021 and December 31, 2020, we had outstanding cross currency swap agreements with a combined notional amount of $834.8 million and $855.1 million, respectively. The agreements are accounted for as either cash flow hedges, to hedge foreign currency fluctuations on certain intercompany debt, or as net investment hedges to manage our exposure to fluctuations in the Euro-U.S. Dollar exchange rate. We had deferred foreign currency losses of $20.3 million and $32.8 million at June 30, 2021 and December 31, 2020, respectively, in Accumulated other comprehensive loss associated with our cross currency swap activity. The periodic interest settlements related to our cross currency swap agreements are classified as operating activities. The cash flows that relate to principal balances are classified as financing activities for the cash flow hedges on intercompany debt and investing activities for the net investment hedges.

In January 2021, one of our cross currency swap agreements which was accounted for as a cash flow hedge matured, resulting in a net cash payment of $14.7 million. The net cash payment is included within financing activities on the Condensed Consolidated Statements of Cash Flows.

Fair value measurements

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Assets and liabilities measured at fair value are classified using the following hierarchy, which is based upon the transparency of inputs to the valuation as of the measurement date:

Level 1:	Valuation is based on observable inputs such as quoted market prices (unadjusted) for identical assets or liabilities in active markets.
Level 2:	Valuation is based on inputs such as quoted market prices for similar assets or liabilities in active markets or other inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.
Level 3:	Valuation is based upon other unobservable inputs that are significant to the fair value measurement.

In making fair value measurements, observable market data must be used when available. When inputs used to measure fair value fall within different levels of the hierarchy, the level within which the fair value measurement is categorized is based on the lowest level input that is significant to the fair value measurement.

Fair value of financial instruments

The following methods were used to estimate the fair values of each class of financial instruments: 

•short-term financial instruments (cash and cash equivalents, accounts and notes receivable, accounts and notes payable and variable-rate debt) — recorded amount approximates fair value because of the short maturity period;

•long-term fixed-rate debt, including current maturities — fair value is based on market quotes available for issuance of debt with similar terms, which are inputs that are classified as Level 2 in the valuation hierarchy defined by the accounting guidance;

•foreign currency contract agreements — fair values are determined through the use of models that consider various assumptions, including time value, yield curves, as well as other relevant economic measures, which are inputs that are classified as Level 2 in the valuation hierarchy defined by the accounting guidance; and

•deferred compensation plan assets (mutual funds, common/collective trusts and cash equivalents for payment of certain non-qualified benefits for retired, terminated and active employees) — fair value of mutual funds and cash equivalents are based on quoted market prices in active markets that are classified as Level 1 in the valuation hierarchy defined by the accounting guidance; fair value of common/collective trusts are valued at net asset value (“NAV”), which is based on the fair value of the underlying securities owned by the fund and divided by the number of shares outstanding.

The recorded amounts and estimated fair values of total debt, excluding unamortized issuance costs and discounts, were as follows:

	June 30, 2021				December 31, 2020
In millions	Recorded Amount		Fair Value		Recorded Amount		Fair Value
Variable rate debt	$	216.1	$	216.1	$	236.1	$	236.1
Fixed rate debt	507.6		577.8		611.4		695.4
Total debt	$	723.7	$	793.9	$	847.5	$	931.5

Financial assets and liabilities measured at fair value on a recurring and nonrecurring basis were as follows:

Total recurring fair value measurements	$	12.2	$	(69.6)	$	—	$	10.4	$	(47.0)

12.Income Taxes

We manage our affairs so that we are centrally managed and controlled in the United Kingdom (“U.K.”) and therefore have our tax residency in the U.K. The provision for income taxes consists of provisions for the U.K. and international income taxes. We operate in an international environment with operations in various locations outside the U.K. Accordingly, the consolidated income tax rate is a composite rate reflecting the earnings in the various locations and the applicable rates.

17

Pentair plc and Subsidiaries

Notes to condensed consolidated financial statements (unaudited)

The effective income tax rate for the six months ended June 30, 2021 was 14.7%, compared to 25.3% for the six months ended June 30, 2020. We continue to actively pursue initiatives to reduce our effective tax rate. The tax rate in any quarter can be affected positively or negatively by adjustments that are required to be reported in the specific quarter of resolution.

The liability for uncertain tax positions was $46.6 million and $46.3 million at June 30, 2021 and December 31, 2020, respectively. We record penalties and interest related to unrecognized tax benefits in Provision for income taxes and Net interest expense, respectively, on the Condensed Consolidated Statements of Operations and Comprehensive Income, which is consistent with our past practices.

13.Benefit Plans

Components of net periodic benefit expense for our pension plans for the three and six months ended June 30, 2021 and 2020 were as follows:

	Three months ended				Six months ended
In millions	June 30, 2021		June 30, 2020		June 30, 2021		June 30, 2020
Service cost	$	0.7	$	0.8	$	1.4	$	1.6
Interest cost	0.5		0.7		1.0		1.4
Expected return on plan assets	(0.1)		(0.2)		(0.2)		(0.4)
Net periodic benefit expense	$	1.1	$	1.3	$	2.2	$	2.6

Components of net periodic benefit expense for our other post-retirement plans for the three and six months ended June 30, 2021 and 2020 were not material.

14.Shareholders’ Equity

Share repurchases

In May 2018, the Board of Directors authorized the repurchase of our ordinary shares up to a maximum dollar limit of $750.0 million (the “2018 Authorization”). The 2018 authorization expired on May 31, 2021. In December 2020, the Board of Directors authorized the repurchase of our ordinary shares up to a maximum dollar limit of $750.0 million (the “2020 Authorization”). The 2020 Authorization expires on December 31, 2025. The 2020 Authorization supplemented the 2018 Authorization.

During the six months ended June 30, 2021, we repurchased 0.8 million of our ordinary shares for $50.0 million under the 2018 Authorization. As of June 30, 2021, we had $750.0 million available for share repurchases under the 2020 Authorization.

Dividends payable

On May 4, 2021, the Board of Directors declared a quarterly cash dividend of $0.20, payable on August 6, 2021 to shareholders of record at the close of business on July 23, 2021. As a result, the balance of dividends payable included in Other current liabilities on our Condensed Consolidated Balance Sheets was $33.2 million at both June 30, 2021 and December 31, 2020, respectively.

15.Segment Information

We evaluate performance based on net sales and segment income (loss) and use a variety of ratios to measure performance of our reporting segments. These results are not necessarily indicative of the results of operations that would have occurred had each segment been an independent, stand-alone entity during the periods presented. Segment income (loss) represents equity income of unconsolidated subsidiaries and operating income exclusive of intangible amortization, certain acquisition related expenses, costs of restructuring and transformation activities, impairments and other unusual non-operating items.

16.Commitments and Contingencies

Legal proceedings

We have been, and in the future may be, made parties to a number of actions filed or have been, and in the future may be, given notice of potential claims relating to the conduct of our business, including those relating to commercial, regulatory or contractual disputes with suppliers, authorities, customers or parties to acquisitions and divestitures, intellectual property matters, environmental, asbestos, safety and health matters, product liability, the use or installation of our products, consumer matters, and employment and labor matters.

While we believe that a material impact on our consolidated financial position, results of operations or cash flows from any such future claims or potential claims is unlikely, given the inherent uncertainty of litigation, a remote possibility exists that a future adverse ruling or unfavorable development could result in future charges that could have a material adverse impact. We do and will continue to periodically reexamine our estimates of probable liabilities and any associated expenses and receivables and make appropriate adjustments to such estimates based on experience and developments in litigation. As a result, the current estimates of the potential impact on our consolidated financial position, results of operations and cash flows for the proceedings and claims described in the notes to our consolidated financial statements could change in the future.

Environmental matters

We have been named as defendant, target or a potentially responsible party in a number of environmental clean-ups relating to our current or former business units. Accruals for environmental matters are recorded on a site-by-site basis when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated, based on current law and existing technologies. It can be difficult to estimate reliably the final costs of investigation and remediation due to various factors. In our opinion, the amounts accrued are appropriate based on facts and circumstances as currently known. As of June 30, 2021 and December 31, 2020, our recorded reserves for environmental matters were not material.

Product liability claims

We are subject to various product liability lawsuits and personal injury claims. A substantial number of these lawsuits and claims are insured and accrued for by Penwald, our captive insurance subsidiary. Penwald records a liability for these claims based on actuarial projections of ultimate losses. For all other claims, accruals covering the claims are recorded, on an undiscounted basis, when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated based on existing information. The accruals are adjusted periodically as additional information becomes available. We have not experienced significant unfavorable trends in either the severity or frequency of product liability lawsuits or personal injury claims.

Warranties and guarantees

In connection with our disposition of businesses or product lines, we may agree to indemnify purchasers for various potential liabilities relating to the sold business, such as pre-closing tax, product liability, warranty, environmental, or other obligations. The subject matter, amounts and duration of any such indemnification obligations vary for each type of liability indemnified and may vary widely from transaction to transaction.

Generally, the maximum obligations under such indemnifications are not explicitly stated and as a result, the overall amount of these obligations cannot be reasonably estimated. Historically, we have not made significant payments for these indemnifications. We believe that if we were to incur a loss in any of these matters, the loss would not have a material adverse effect on our financial position, results of operations or cash flows.

We recognize, at the inception of a guarantee, a liability for the fair value of the obligation undertaken in issuing the guarantee. In connection with the disposition of the Valves & Controls business, we agreed to indemnify Emerson Electric Co. for certain pre-closing tax liabilities. We have recorded a liability representing the fair value of our expected future obligation for this matter.

We provide service and warranty policies on our products. Liability under service and warranty policies is based upon a review of historical warranty and service claim experience. Adjustments are made to accruals as claim data and historical experience warrant.

Stand-by letters of credit, bank guarantees and bonds

In certain situations, Tyco International Ltd., Pentair Ltd.’s former parent company (“Tyco”), guaranteed performance by the flow control business of Pentair Ltd. (“Flow Control”) to third parties or provided financial guarantees for financial commitments of Flow Control. In situations where Flow Control and Tyco were unable to obtain a release from these guarantees in connection with the spin-off of Flow Control from Tyco, we will indemnify Tyco for any losses it suffers as a result of such guarantees.

In the ordinary course of business, we are required to commit to bonds, letters of credit and bank guarantees that require payments to our customers for any non-performance. The outstanding face value of these instruments fluctuates with the value of our projects in process and in our backlog. In addition, we issue financial stand-by letters of credit primarily to secure our performance to third parties under self-insurance programs.

As of June 30, 2021 and December 31, 2020, the outstanding value of bonds, letters of credit and bank guarantees totaled $98.9 million and $99.1 million, respectively.

Overview

The terms “us,” “we,” “our” or “Pentair” refer to Pentair plc and its consolidated subsidiaries. At Pentair, we believe the health of our world depends on reliable access to clean water. We deliver a comprehensive range of smart, sustainable water solutions to homes, business and industry around the world. Our industry leading and proven portfolio of solutions enables our customers to access clean, safe water, reduce water consumption, and recover and reuse it. Whether it’s improving, moving or helping people enjoy water, we help manage the world’s most precious resource. We are comprised of two reporting segments: Consumer Solutions and Industrial & Flow Technologies. For the first six months of 2021, the Consumer Solutions and Industrial & Flow Technologies segments represented approximately 61% and 39% of total revenues, respectively. We classify our operations into business segments based primarily on types of products offered and markets served:

•Consumer Solutions — This segment designs, manufactures and sells energy-efficient residential and commercial pool equipment and accessories, and commercial and residential water treatment products and systems. Residential and commercial pool equipment and accessories include pumps, filters, heaters, lights, automatic controls, automatic cleaners, maintenance equipment and pool accessories. Water treatment products and systems include pressure tanks, control valves, activated carbon products, conventional filtration products, and point-of-entry and point-of-use systems. Applications for our pool business’s products include residential and commercial pool maintenance, repair, renovation, service and construction. Our water treatment products and systems are used in residential whole home water filtration, drinking water filtration and water softening solutions in addition to commercial total water management and filtration in foodservice operations. The primary focus of this segment is business-to-consumer.

22

•Industrial & Flow Technologies — This segment manufactures and sells a variety of fluid treatment and pump products and systems, including pressure vessels, gas recovery solutions, membrane bioreactors, wastewater reuse systems and advanced membrane filtration, separation systems, water disposal pumps, water supply pumps, fluid transfer pumps, turbine pumps, solid handling pumps, and agricultural spray nozzles, while serving the global residential, commercial and industrial markets. These products and systems are used in a range of applications, including fluid delivery, ion exchange, desalination, food and beverage, separation technologies for the oil and gas industry, residential and municipal wells, water treatment, wastewater solids handling, pressure boosting, circulation and transfer, fire suppression, flood control, agricultural irrigation and crop spray. The primary focus of this segment is business-to-business.

COVID-19 Pandemic Update

In March 2020, the World Health Organization declared the COVID-19 outbreak a pandemic. The COVID-19 pandemic continues to persist throughout the United States (“U.S.”) and the world, with the continued potential for significant impact. The COVID-19 pandemic has resulted in governments around the world implementing stringent measures to help control the spread of the virus, including quarantines, “shelter-in-place” and “stay-at-home” orders, travel restrictions, business curtailments, limits on gatherings, and other measures. In addition, governments and central banks in several parts of the world have enacted fiscal and monetary stimulus measures to counteract the economic impacts of the COVID-19 pandemic.

Our businesses generally have been and continue to be considered essential under applicable government-mandated orders which has allowed us to maintain business continuity at substantially all of our manufacturing facilities throughout the COVID-19 pandemic. While our facilities have remained operational during the first half of 2021, we continue to experience various degrees of manufacturing cost pressures and inefficiencies as a result of supply chain issues and, in certain businesses, increased demand. Although we regularly monitor the financial health and operations of companies in our supply chain, and use alternative suppliers when necessary and available, financial hardship or government restrictions on our suppliers or sub-suppliers caused by the COVID-19 pandemic could cause a disruption in our ability to obtain raw materials or components required to manufacture our products and adversely affect our operations. Further, as the COVID-19 pandemic conditions improve and economic activity increases, we have experienced supply chain challenges, including increased lead times, as well as inflation of raw materials, logistics and labor costs due to availability constraints and high demand. We expect the inflationary trends to continue throughout the remainder of 2021.

Our Consumer Solutions segment delivered significant growth in the first six months of 2021 led by continued strength in our pool and residential water treatment businesses. The high level of demand in these businesses continued as consumers invested in their homes and backyards. Demand in our commercial water treatment business improved in the second quarter of 2021 as the restaurant and hospitality industries began to reopen.

Our Industrial & Flow Technologies segment had strong growth in the first six months of 2021 mainly driven by increased volume within our residential and irrigation flow businesses due to high demand in the residential vertical. Our commercial flow business experienced increased sales in the first half of 2021 due to strong demand in our water supply and water disposal product lines. Demand in our infrastructure business has stabilized but we remain disciplined in our project selection. In our industrial filtration business, demand is mostly driven by customer capital spending, which saw recovery in the second quarter of 2021 in most industries served.

We maintain our commitment to protect the health and safety of our employees, customers, and suppliers by continuing our enhanced safety protocols for those on-site at our manufacturing facilities and for those who provide manufacturing-support activities. In addition, employees who do not need to be physically present at our facilities and sites to perform their job responsibilities generally continue to work from home and essential business travel remains the main travel activity.

The extent of the COVID-19 pandemic’s effect on our operational and financial performance in the future will depend on future developments, including the duration, geographic location and intensity of the pandemic, the impact of virus variants, the rate of vaccinations, our continued ability to manufacture and distribute our products, as well as any future actions that may be taken by governmental authorities or by us relating to the pandemic. For more information regarding factors and events that may impact our business, results of operations and financial condition as a result of the COVID-19 pandemic, see “Risk Factors - Risks Related to the COVID-19 Pandemic” included in Item 1A. “Risk Factors” in our 2020 Annual Report on Form 10-K.

23

Transformation Program

During the second quarter of 2021, we launched and committed resources to a program designed to accelerate growth and drive margin expansion through transformation of our business model to drive operational excellence, reduce complexity and streamline our processes (the “Transformation Program”). The Transformation Program is structured in multiple phases and is expected to empower us to work more efficiently and optimize our business to better serve our customers while meeting our financial objectives.

We are targeting at least 300 basis points of margin expansion by 2025 through the following Transformation Program pillars:

•reducing business and product complexity;

•developing a future state digital enterprise by eliminating non-value add activities, streamlining processes and using automation to increase productivity;

•modernizing general and administrative expenses, and

•delivering decision making speed through improved processes and analytics.

Throughout the remainder of 2021 and beyond we expect to incur transformation costs including and related to labor restructuring, non-labor restructuring, IT investments and design and execution charges.

Key Trends and Uncertainties Regarding Our Existing Business

The following trends and uncertainties affected our financial performance in the first six months of 2021 and/or may impact our results in the future:

•There are many uncertainties regarding the COVID-19 pandemic, including the anticipated duration and severity of the pandemic, the spread of increasing number of virus variants, the extent of worldwide social, political and economic disruption it may continue to cause and the development and distribution of vaccines to address the COVID-19 virus. The broader implications of the COVID-19 pandemic on our business, financial condition, results of operations and cash flows cannot be determined at this time, and ultimately will be affected by a number of evolving factors including the length of time that the pandemic continues and the impact of vaccines on it, the impact of virus variants, the rate of vaccinations, the pandemic’s effect on the demand for our products and services, our supply chain, and our manufacturing capacity, as well as the impact of governmental regulations imposed in response to the pandemic. See further discussion above under “COVID-19 Pandemic Update” for key trends and uncertainties with regard to the COVID-19 pandemic.

•During 2020 and the first half of 2021, we executed certain business restructuring initiatives unrelated to the COVID-19 pandemic aimed at reducing our fixed cost structure and realigning our business. We expect these actions to continue throughout the remainder of 2021 and to drive margin growth.

•In 2021, we created a transformation office and launched and committed resources to the Transformation Program designed to accelerate growth and drive margin expansion by driving operational excellence, reducing complexity and streamlining our processes. We expect to implement Transformation Program initiatives and incur transformation costs throughout the remainder of 2021 and beyond.

•We have identified specific product and geographic market opportunities that we find attractive and continue to pursue, both within and outside the U.S. We are reinforcing that our businesses more effectively address these opportunities through research and development and additional sales and marketing resources. Unless we successfully penetrate these markets, our core sales growth will likely be limited or may decline.

•During the first half of 2021, we experienced supply chain challenges, including increased lead times, and inflationary increases of raw materials such as metals, resins and electronics, logistics and labor costs due to availability constraints and high demand. While we have taken pricing actions and we strive for productivity improvements that could help offset these cost increases, we expect supply chain pressures and inflationary cost increases to continue for the remainder of 2021, which may continue thereafter and could negatively impact our results of operations.

24

In 2021, our operating objectives remain to focus on delivering our core while continuing to build out our future. We expect to execute these objectives by:

•Delivering revenue growth in our core businesses;

•Delivering income and cash by managing price/cost inflation, prioritization of growth investments and addressing the cost structures as necessary;

•Continued focus on capital allocation through:

◦Commitment to maintain our investment grade rating;

◦Return cash to shareholders through dividends and buybacks; and

◦Supplement our business with strategically-aligned mergers and acquisitions.

•Focused growth initiatives that accelerate our investments in digital, technology and services expansion;

•Identification, building and implementation of Transformation Program initiatives that will drive operational excellence, reduce complexity and improve our organizational structure; and

•Building a high performance growth culture and delivering on our commitments while living our Win Right values.

Net sales

The components of the consolidated net sales change from the prior period were as follows:

	Three months ended June 30, 2021		Six months ended June 30, 2021
	over the prior year period		over the prior year period
Volume	26.1	%	21.7	%
Price	1.6		1.4
Core growth	27.7		23.1
Acquisition	1.7		1.3
Currency	2.5		2.6
Total	31.9	%	27.0	%

The 31.9 and 27.0 percent increases in net sales in the second quarter and first half, respectively, of 2021 from 2020 were primarily driven by:

•volume increase in our Consumer Solutions segment mainly driven by continued robust demand in our pool and residential water treatment businesses;

•volume increase in our residential and irrigation flow businesses in our Industrial & Flow Technologies segment due to strong demand across all product lines in those businesses;

•selective increases in selling prices to mitigate inflationary cost increases; and

•favorable foreign currency effects compared to the second quarter and first six month of the prior year.

27

Gross profit

The 1.8 and 1.4 percentage point increases in gross profit as a percentage of net sales in the second quarter and first half, respectively, of 2021 from 2020 were primarily driven by:

•volume expansion in both our Consumer Solutions and Industrial & Flow Technologies segments;

•selective increases in selling prices to mitigate impacts of inflation; and

•increased productivity in both the Consumer Solutions and Industrial & Flow Technologies segments.

This increase was partially offset by:

•inflationary cost increases due to tight supply of raw materials such as metals, resins and electronics; and

•higher logistics and labor costs due to increased demand as well as factory labor wage increases.

Selling, general and administrative expenses (“SG&A”)

The 0.4 percentage point increase in SG&A as a percentage of net sales in the second quarter of 2021 from 2020 was primarily driven by:

•higher employee incentive compensation due to increased sales in our Consumer Solutions and Industrial & Flow Technologies segments;

•restructuring, transformation and other costs of $5.8 million in the second quarter of 2021, compared to $1.1 million in the second quarter of 2020; and

•lower travel and entertainment, trade show and advertising expenses in the second quarter of 2020 due to the government restrictions in place for the COVID-19 pandemic.

This increase was partially offset by:

•lower amortization on definite-lived intangible assets.

The 1.2 percentage point decrease in SG&A as a percentage of net sales in the first half of 2021 from 2020 was primarily driven by:

•reduction in travel and entertainment, trade show and advertising expenses compared to the prior year due to the COVID-19 pandemic restrictions not beginning until March of 2020;

•legal accrual reductions of $2.4 million in the first quarter of 2021; and

•leverage on certain fixed costs due to the significant increase in sales year over year.

This decrease was partially offset by:

•higher employee incentive compensation due to increased sales in our Consumer Solutions and Industrial & Flow Technologies segments; and

•restructuring, transformation and other costs of $7.3 million in the first six months of 2021, compared to $3.5 million in the first six months of 2020.

Net interest expense

The 50.6 and 39.0 percent decreases in net interest expense in the second quarter and first half, respectively, of 2021 from 2020 were primarily driven by:

•strong cash flows in 2021 used to repay senior fixed notes that matured as well as reduce variable debt leading to overall lower debt levels compared to the same periods of the prior year; and

•lower interest rates on outstanding variable debt.

28

Provision for income taxes

The 12.9 and 10.6 percentage point decreases in the effective tax rate in the second quarter and first half, respectively, of 2021 from 2020 were primarily driven by:

•the unfavorable impact of discrete items, including items related to the Coronavirus Aid, Relief, and Economic Security Act and items related to final regulations as part of the Tax Cuts and Jobs Act of 2017 that limit the deductibility of interest expense for U.S. tax purposes that occurred during the second quarter and first half of 2020 that did not occur in 2021.

These decreases were partially offset by:

•the unfavorable mix of global earnings.

SEGMENT RESULTS OF OPERATIONS

The summary that follows provides a discussion of the results of operations of our two reportable segments (Consumer Solutions and Industrial & Flow Technologies). Each of these segments is comprised of various product offerings that serve multiple end users.

We evaluate performance based on net sales and segment income and use a variety of ratios to measure performance of our reporting segments. Segment income represents equity income of unconsolidated subsidiaries and operating income exclusive of intangible amortization, certain acquisition related expenses, costs of restructuring and transformation activities, impairments and other unusual non-operating items.

BACKLOG OF ORDERS BY SEGMENT

In millions	June 30, 2021		December 31, 2020		$ Change		% Change
Consumer Solutions	$	1,173.7	$	459.1	$	714.6	155.7	%
Industrial & Flow Technologies	391.1		288.7		102.4		35.5	%
Total	$	1,564.8	$	747.8	$	817.0	109.3	%

The majority of our backlog is short cycle in nature with shipments within one year from when a customer places an order and a substantial portion of our revenues has historically resulted from orders received and products delivered in the same month. A portion of our backlog, particularly from orders for major capital projects, can take more than one year depending on the size and type of order. We record, as part of our backlog, all orders from external customers, which represent firm commitments, and are supported by a purchase order or other legitimate contract. Our backlog of orders is dependent upon when customers place orders and is not necessarily an indicator of our expected results for our 2021 net sales.

The increase in our backlog from December 31, 2020 to June 30, 2021 was driven by a significant increase in orders due to higher than anticipated demand in certain of our residential and commercial businesses coupled with continuing supply chain disruptions and labor availability challenges.

LIQUIDITY AND CAPITAL RESOURCES

We generally fund cash requirements for working capital, capital expenditures, equity investments, acquisitions, debt repayments, dividend payments and share repurchases from cash generated from operations, availability under existing committed revolving credit facilities and in certain instances, public and private debt and equity offerings. Our primary revolving credit facilities have generally been adequate for these purposes, although we have negotiated additional credit facilities or completed debt and equity offerings as needed to allow us to complete acquisitions.

We experience seasonal cash flows primarily due to seasonal demand in a number of markets. Consistent with historical trends, we experienced seasonal cash usage in the first quarter of 2021 and drew on our revolving credit facility to fund our operations. This cash usage reversed in the second quarter as the seasonality of our businesses peaked and generated significant cash to fund our operations.

End-user demand for pool and certain pumping equipment has followed warm weather trends and historically has been at seasonal highs from April to August. The magnitude of the sales spike has been partially mitigated by employing some advance sale “early buy” programs (generally including extended payment terms and/or additional discounts). Demand for residential and agricultural water systems is also impacted by weather patterns, particularly by heavy flooding and droughts.

We expect to continue to have sufficient cash and borrowing capacity to support working capital needs and capital expenditures, to pay interest and service debt and to pay dividends to shareholders quarterly. We believe our existing liquidity position, coupled with our currently anticipated operating cash flows, will be sufficient to meet our cash needs arising in the ordinary course of business for the next twelve months. Although the impact of the COVID-19 pandemic on our future results is uncertain, we believe we are well-positioned to manage our business and have the ability and sufficient capacity to meet these cash requirements by using available cash, internally generated funds and borrowing under our committed and uncommitted credit facilities. We are committed to maintaining investment grade credit ratings and a solid liquidity position.

Operating activities

The $361.0 million in net cash provided by operating activities of continuing operations in the first six months of 2021 primarily reflects $302.6 million of net income from continuing operations, net of non-cash depreciation and amortization. Additionally, the Company had a cash inflow of $47.2 million as a result of changes in net working capital, primarily the result of collections of accounts receivables on higher sales, increased accounts payables resulting from inventory purchases to meet demand and increased sales leading to higher accrued rebates and incentives.

The $266.5 million in net cash provided by operating activities of continuing operations in the first six months of 2020 primarily reflects $183.9 million of net income from continuing operations, net of non-cash depreciation and amortization. Additionally, the Company had a cash inflow of $59.1 million as a result of changes in net working capital, primarily the result of collections on accounts receivables from our early buy programs in the pool business that became due in the second quarter.

Investing activities

Net cash used for investing activities in the first six months of 2021 reflects net cash paid of $82.8 million for the Ken’s Beverage, Inc. acquisition, capital expenditures of $24.3 million and proceeds from the sale of property and equipment of $3.5 million.

Net cash used for investing activities in the first six months of 2020 primarily reflects capital expenditures of $30.5 million and cash paid for acquisitions in our Consumer Solutions reporting segment of $28.5 million, net of cash acquired.

Financing activities

Net cash used for financing activities in the first six months of 2021 primarily relates to the repayment of $103.8 million senior fixed notes, net borrowings of revolving long-term debt of $20.0 million, $50.0 million of share repurchases, dividend payments of $66.7 million and payments upon the maturity of cross currency swaps of $14.7 million.

Net cash used for financing activities in the first six months of 2020 primarily relates to $115.2 million of share repurchases and dividend payments of $63.7 million.

Free Cash Flow

In addition to measuring our cash flow generation or usage based upon operating, investing and financing classifications included in the Condensed Consolidated Statements of Cash Flows, we also measure our free cash flow. We have a long-term goal to consistently generate free cash flow greater than 100 percent conversion of net income. Free cash flow is a non-GAAP financial measure that we use to assess our cash flow performance. We believe free cash flow is an important measure of liquidity because it provides us and our investors a measurement of cash generated from operations that is available to pay dividends, repurchase shares and repay debt. In addition, free cash flow is used as a criterion to measure and pay compensation-based incentives. Our measure of free cash flow may not be comparable to similarly titled measures reported by other companies.

The following table is a reconciliation of free cash flow:

	Six months ended

Debt and Capital

Pentair, Pentair Finance S.à r.l (“PFSA“) and Pentair, Inc. are parties to a credit agreement (the “Senior Credit Facility”), with Pentair as guarantor and PFSA and Pentair, Inc. as borrowers, providing for a $900.0 million senior unsecured revolving credit facility. The Senior Credit Facility has a maturity date of April 25, 2023. Borrowings under the Senior Credit Facility bear interest at a rate equal to an adjusted base rate or the London Interbank Offered Rate, plus, in each case, an applicable margin. The applicable margin is based on, at PFSA’s election, Pentair’s leverage level or PFSA’s public credit rating.

The Senior Credit Facility provides for the extension of term loans in an aggregate amount of $200.0 million (the “Term Loans”). We have utilized the term loan extension since December 2019.. The Term Loans are in addition to the revolving credit facility commitment. In addition, PFSA has the option to further increase the Senior Credit Facility in an aggregate amount of up to $300.0 million, through a combination of increases to the total commitment amount of the revolving credit facility and/or one or more tranches of term loans in addition to the Term Loans, subject to customary conditions, including the commitment of the participating lenders.

PFSA is authorized to sell short-term commercial paper notes to the extent availability exists under the Senior Credit Facility. PFSA uses the Senior Credit Facility as back-up liquidity to support 100% of commercial paper outstanding. PFSA had no commercial paper outstanding as of June 30, 2021 and December 31, 2020.

In 2020, the commercial paper market began to experience high levels of volatility due to uncertainty related to the COVID-19 pandemic. The volatility impacted both market access to and pricing of commercial paper. As a cost mitigation action, we withdrew our credit ratings to access the commercial paper market and continued to use the revolving credit facility, along with cash generated from operations, to fund our general operations. As of June 30, 2021, total availability under the Senior Credit Facility was $883.9 million.

Our debt agreements contain various financial covenants, but the most restrictive covenants are contained in the Senior Credit Facility. The Senior Credit Facility contains covenants requiring us not to permit (i) the ratio of our consolidated debt (net of our consolidated unrestricted cash in excess of $5.0 million but not to exceed $250.0 million) to our consolidated net income (excluding, among other things, non-cash gains and losses) before interest, taxes, depreciation, amortization and non-cash share-based compensation expense (“EBITDA”) on the last day of any period of four consecutive fiscal quarters to exceed 3.75 to 1.00 (the “Leverage Ratio”) and (ii) the ratio of our EBITDA to our consolidated interest expense, for the same period to be less than 3.00 to 1.00 as of the end of each fiscal quarter. For purposes of the Leverage Ratio, the Senior Credit Facility provides for the calculation of EBITDA giving pro forma effect to certain acquisitions, divestitures and liquidations during the period to which such calculation relates. As of June 30, 2021, we were in compliance with all financial covenants in our debt agreements, and there was no material uncertainty about our ongoing ability to meet these covenants.

34

In addition to the Senior Credit Facility, we have various other credit facilities with an aggregate availability of $21.4 million, of which there were no outstanding borrowings at June 30, 2021. Borrowings under these credit facilities bear interest at variable rates.

We have no fixed rate senior notes maturing in the next twelve months.

As of June 30, 2021, we have $60.1 million of cash held in certain countries in which the ability to repatriate is limited due to local regulations or significant potential tax consequences.

Share repurchases

In May 2018, the Board of Directors authorized the repurchase of our ordinary shares up to a maximum dollar limit of $750.0 million (the “2018 Authorization”). The 2018 authorization expired on May 31, 2021. In December 2020, the Board of Directors authorized the repurchase of our ordinary shares up to a maximum dollar limit of $750.0 million (the “2020 Authorization”). The 2020 Authorization expires on December 31, 2025. The 2020 Authorization supplemented the 2018 Authorization.

During the six months ended June 30, 2021, we repurchased 0.8 million of our ordinary shares for $50.0 million under the 2018 Authorization. As of June 30, 2021, we had $750.0 million available for share repurchases under the 2020 Authorization.

Dividends payable

On May 4, 2021, the Board of Directors declared a quarterly cash dividend of $0.20, payable on August 6, 2021 to shareholders of record at the close of business on July 23, 2021. As a result, the balance of dividends payable included in Other current liabilities on our Condensed Consolidated Balance Sheets was $33.2 million at both June 30, 2021 and December 31, 2020, respectively.

We paid dividends in the first six months of 2021 of $66.7 million, or $0.40 per ordinary share compared with $63.7 million, or $0.38 per ordinary share, in the prior year period.

Under Irish law, the payment of future cash dividends and repurchases of shares may be paid only out of Pentair plc’s “distributable reserves” on its statutory balance sheet. Pentair plc is not permitted to pay dividends out of share capital, which includes share premiums. Distributable reserves may be created through the earnings of the Irish parent company and through a reduction in share capital approved by the Irish High Court. Distributable reserves are not linked to a U.S. generally accepted accounting principles (“GAAP”) reported amount (e.g., retained earnings). Our distributable reserve balance was $8.8 billion as of December 31, 2020.

Supplemental guarantor information

Pentair plc (the “Parent Company Guarantor”), fully and unconditionally, guarantees the senior notes of PFSA (the “Subsidiary Issuer”). The Subsidiary Issuer is a Luxembourg private limited liability company and 100 percent-owned subsidiary of the Parent Company Guarantor.

The Parent Company Guarantor is a holding company established to own directly and indirectly substantially all of its operating and other subsidiaries. The Subsidiary Issuer is a holding company formed to own directly and indirectly substantially all of its operating and other subsidiaries and to issue debt securities, including the senior notes. The Parent Company Guarantor’s principal source of cash flow, including cash flow to make payments on the senior notes pursuant to the guarantees, is dividends from its subsidiaries. The Subsidiary Issuer’s principal source of cash flow is interest income from its subsidiaries. None of the subsidiaries of the Parent Company Guarantor or the Subsidiary Issuer is under any direct obligation to pay or otherwise fund amounts due on the senior notes or the guarantees, whether in the form of dividends, distributions, loans or other payments. In addition, there may be statutory and regulatory limitations on the payment of dividends from certain subsidiaries of the Parent Company Guarantor or the Subsidiary Issuer. If such subsidiaries are unable to transfer funds to the Parent Company Guarantor or the Subsidiary Issuer and sufficient cash or liquidity is not otherwise available, the Parent Company Guarantor or the Subsidiary Issuer may not be able to make principal and interest payments on their outstanding debt, including the senior notes or the guarantees.

35

The following table presents summarized financial information as of June 30, 2021 and December 31, 2020 for the Parent Company Guarantor and Subsidiary Issuer on a combined basis after elimination of (i) intercompany transactions and balances among the guarantors and issuer and (ii) equity in earnings from and investments in any subsidiary that is a non-Guarantor or issuer.

Basis of Presentation and Responsibility for Interim Financial Statements

Basis of Presentation and Responsibility for Interim Financial Statements

The accompanying unaudited condensed consolidated financial statements of Pentair plc and its subsidiaries (“we,” “us,” “our,” “Pentair,” or the “Company”) have been prepared following the requirements of the U.S. Securities and Exchange Commission (“SEC”) for interim reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by accounting principles generally accepted in the United States of America (“GAAP”) can be condensed or omitted.

We are responsible for the unaudited condensed consolidated financial statements included in this document. The financial statements include all normal recurring adjustments that are considered necessary for the fair presentation of our financial position and operating results. As these are condensed financial statements, one should also read our consolidated financial statements and notes thereto, which are included in our Annual Report on Form 10-K for the year ended December 31, 2020.

Revenues, expenses, cash flows, assets and liabilities can and do vary during each quarter of the year. Therefore, the results and trends in these interim financial statements may not be indicative of those for a full year.

In March 2020, the World Health Organization declared the novel coronavirus 2019 (“COVID-19”) a global pandemic. The COVID-19 pandemic has had and may continue to have an unfavorable impact on certain parts of our business. The broader implications of the COVID-19 pandemic on our business, financial condition and results of operations remain uncertain and will depend on certain developments, including the duration and severity of the COVID-19 pandemic, the impact of virus variants, the rate of vaccinations, the COVID-19 pandemic’s impact on our customers and suppliers and the range of governmental and community reactions to the pandemic. We may continue to experience reduced customer demand in certain parts of our business or constrained supply that could materially and adversely impact our business, financial condition, results of operations, liquidity and cash flows in future periods.

Our fiscal year ends on December 31. We report our interim quarterly periods on a calendar quarter basis.

Revenue

We disaggregate our revenue from contracts with customers by segment, geographic location and vertical, as we believe these best depict how the nature, amount, timing and uncertainty of our revenue and cash flows are affected by economic factors. Refer to Note 15 for revenue disaggregated by segment.

Geographic net sales information, based on geographic destination of the sale, was as follows:

	Three months ended				Six months ended

Consolidated net sales	$	941.1	$	713.3	$	1,807.0	$	1,423.3

Performance obligations

On June 30, 2021, we had $83.3 million of remaining performance obligations on contracts with an original expected duration of one year or more. We expect to recognize the majority of our remaining performance obligations on these contracts within the next 12 to 18 months.

Contract assets and liabilities

Contract assets and liabilities consisted of the following:

In millions	June 30, 2021		December 31, 2020		$ Change		% Change
Contract assets	$	52.3	$	50.1	$	2.2	4.4	%
Contract liabilities	35.7		27.5		8.2		29.8	%
Net contract assets	$	16.6	$	22.6	$	(6.0)	(26.5)	%

The $6.0 million decrease in net contract assets from December 31, 2020 to June 30, 2021 was primarily the result of timing of milestone payments and impact of foreign currency fluctuations. Approximately 65% of our contract liabilities at December 31, 2020 were recognized in revenue in the first half of 2021. There were no impairment losses recognized on our contract assets for the three months ended June 30, 2021.

Acquisitions

Acquisitions

On May 19, 2021, as part of our Consumer Solutions reporting segment, we completed the acquisition of Ken’s Beverage, Inc. for $82.8 million in cash, net of cash acquired. The excess of purchase price over tangible net assets acquired has been preliminarily allocated to goodwill in the amount of $29.3 million, all of which is expected to be deductible for income tax purposes. Identifiable intangible assets acquired consisted of $38.0 million of definite-lived customer relationships with an estimated useful life of 22 years.

In 2020, our Consumer Solutions reporting segment completed acquisitions with purchase prices totaling $58.0 million in cash, net of cash acquired.

The pro forma impact of these acquisitions is not material.

Share-based Payment Arrangement [Abstract]

Share Plans

Total share-based compensation expense for the three and six months ended June 30, 2021 and 2020 was as follows:

	Three months ended				Six months ended
In millions	June 30, 2021		June 30, 2020		June 30, 2021		June 30, 2020
Restricted stock units	$	3.6	$	3.1	$	7.0	$	6.3
Stock options	0.9		0.6		1.8		1.6
Performance share units	6.5		0.5		7.8		2.5
Total share-based compensation expense	$	11.0	$	4.2	$	16.6	$	10.4

In the first quarter of 2021, we issued our annual share-based compensation grants under the Pentair plc 2020 Share and Incentive Plan to eligible employees. The total number of awards issued was approximately 0.7 million, of which 0.3 million were restricted stock units (“RSUs”), 0.3 million were stock options and 0.1 million were performance share units (“PSUs”). The weighted-average grant date fair value of the RSUs, stock options and PSUs issued was $55.42, $12.88, and $52.57, respectively.

We estimated the fair value of each stock option award issued in the annual share-based compensation grant using a Black-Scholes option pricing model, modified for dividends and using the following assumptions:

	2021 Annual Grant
Risk-free interest rate	0.37	%
Expected dividend yield	1.56	%
Expected share price volatility	29.60	%
Expected term (years)	6.5

These estimates require us to make assumptions based on historical results, observance of trends in our share price, changes in option exercise behavior, future expectations and other relevant factors. If other assumptions had been used, share-based compensation expense, as calculated and recorded under the accounting guidance, could have been affected. We based the expected life assumption on historical experience as well as the terms and vesting periods of the options granted. For purposes of determining expected share price volatility, we considered a rolling average of historical volatility measured over a period approximately equal to the expected option term. The risk-free interest rate for periods that coincide with the expected life of the options is based on the United States (“U.S.”) Treasury Department yield curve in effect at the time of grant.

Restructuring and Related Activities [Abstract]

Restructuring and Transformation Programs

Restructuring and Transformation Program

During the second quarter of 2021, we launched and committed resources to a program designed to accelerate growth and drive margin expansion through transformation of our business model to drive operational excellence, reduce complexity and streamline our processes (the “Transformation Program”). The Transformation Program is structured in multiple phases and is expected to empower us to work more efficiently and optimize our business to better serve our customers while meeting our financial objectives.

During the six months ended June 30, 2021 and the year ended December 31, 2020, we initiated and continued execution of actions aimed at reducing our fixed cost structure and realigning our business associated with restructuring and the Transformation Program, including the reduction in headcount of approximately 50 and 175 employees, respectively.

Restructuring and transformation-related costs within Selling, general and administrative expenses in the Condensed Consolidated Statements of Operations and Comprehensive Income included the following: 

	Three months ended				Six months ended

Transformation and other costs	1.9		—		2.1		—

Transformation and other costs primarily consist of professional services, project management and related costs, infrastructure charges to vacate facilities and consolidate operations, and asset impairment and various contract termination costs.

Restructuring and transformation costs by reportable segment were as follows:

Receivables [Abstract]

Accounts Receivable

Accounts Receivable

All trade receivables are reported on our Condensed Consolidated Balance Sheets at the outstanding principal amount adjusted for any allowance for credit losses and write-offs, net of recoveries. We record an allowance for credit losses, reducing our receivables balance to an amount we estimate is collectible from our customers. Estimates used in determining the allowance for credit losses are based on current trends, aging of accounts receivable, periodic credit evaluations of our customers’ financial condition, and historical collection experience as well as reasonable and supportable forecasts of future economic conditions. Write-offs are recorded at the time all collection efforts have been exhausted. We generally do not require collateral. We review our allowance for credit losses on a quarterly basis.

Pentair, Pentair Finance S.à r.l (“PFSA“) and Pentair, Inc. are parties to a credit agreement (the “Senior Credit Facility”), with Pentair as guarantor and PFSA and Pentair, Inc. as borrowers, providing for a $900.0 million senior unsecured revolving credit facility. The Senior Credit Facility has a maturity date of April 25, 2023. Borrowings under the Senior Credit Facility bear interest at a rate equal to an adjusted base rate or the London Interbank Offered Rate, plus, in each case, an applicable margin. The applicable margin is based on, at PFSA’s election, Pentair’s leverage level or PFSA’s public credit rating.

The Senior Credit Facility provides for the extension of term loans in an aggregate amount of $200.0 million (the “Term Loans”). We have utilized the term loan extension since December 2019. The Term Loans are in addition to the revolving credit facility commitment. In addition, PFSA has the option to further increase the Senior Credit Facility in an aggregate amount of up to $300.0 million, through a combination of increases to the total commitment amount of the revolving credit facility and/or one or more tranches of term loans in addition to the Term Loans, subject to customary conditions, including the commitment of the participating lenders.

PFSA is authorized to sell short-term commercial paper notes to the extent availability exists under the Senior Credit Facility. PFSA uses the Senior Credit Facility as back-up liquidity to support 100% of commercial paper outstanding. PFSA had no commercial paper outstanding as of June 30, 2021 and December 31, 2020.

In 2020, the commercial paper market began to experience high levels of volatility due to uncertainty related to the COVID-19 pandemic. The volatility impacted both market access to and pricing of commercial paper. As a cost mitigation action, we withdrew our credit ratings to access the commercial paper market and continued to use the revolving credit facility, along with cash generated from operations, to fund our general operations. As of June 30, 2021, total availability under the Senior Credit Facility was $883.9 million.

Our debt agreements contain various financial covenants, but the most restrictive covenants are contained in the Senior Credit Facility. The Senior Credit Facility contains covenants requiring us not to permit (i) the ratio of our consolidated debt (net of our consolidated unrestricted cash in excess of $5.0 million but not to exceed $250.0 million) to our consolidated net income (excluding, among other things, non-cash gains and losses) before interest, taxes, depreciation, amortization and non-cash share-based compensation expense (“EBITDA”) on the last day of any period of four consecutive fiscal quarters to exceed 3.75 to 1.00 (the “Leverage Ratio”) and (ii) the ratio of our EBITDA to our consolidated interest expense, for the same period to be less than 3.00 to 1.00 as of the end of each fiscal quarter. For purposes of the Leverage Ratio, the Senior Credit Facility provides for the calculation of EBITDA giving pro forma effect to certain acquisitions, divestitures and liquidations during the period to which such calculation relates.

In addition to the Senior Credit Facility, we have various other credit facilities with an aggregate availability of $21.4 million, of which there were no outstanding borrowings at June 30, 2021. Borrowings under these credit facilities bear interest at variable rates.

We have no fixed rate senior notes maturing in the next twelve months.

Debt outstanding, excluding unamortized issuance costs and discounts, at June 30, 2021 matures on a calendar year basis as follows:

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivatives and Financial Instruments

Derivatives and Financial Instruments

Derivative financial instruments

We are exposed to market risk related to changes in foreign currency exchange rates. To manage the volatility related to this exposure, we periodically enter into a variety of derivative financial instruments. Our objective is to reduce, where it is deemed appropriate to do so, fluctuations in earnings and cash flows associated with changes in foreign currency exchange rates. The derivative contracts contain credit risk to the extent that our bank counterparties may be unable to meet the terms of the agreements. The amount of such credit risk is generally limited to the unrealized gains, if any, in such contracts. Such risk is minimized by limiting those counterparties to major financial institutions of high credit quality.

Foreign currency contracts

We conduct business in various locations throughout the world and are subject to market risk due to changes in the value of foreign currencies in relation to our reporting currency, the U.S. dollar. We manage our economic and transaction exposure to certain market-based risks through the use of foreign currency derivative financial instruments. Our objective in holding these derivatives is to reduce the volatility of net earnings and cash flows associated with changes in foreign currency exchange rates. The majority of our foreign currency contracts have an original maturity date of less than one year.

At June 30, 2021 and December 31, 2020, we had outstanding foreign currency derivative contracts with gross notional U.S. dollar equivalent amounts of $10.6 million and $12.4 million, respectively. The impact of these contracts on the Condensed Consolidated Statements of Operations and Comprehensive Income was not material for any period presented.

Cross Currency Swaps

At June 30, 2021 and December 31, 2020, we had outstanding cross currency swap agreements with a combined notional amount of $834.8 million and $855.1 million, respectively. The agreements are accounted for as either cash flow hedges, to hedge foreign currency fluctuations on certain intercompany debt, or as net investment hedges to manage our exposure to fluctuations in the Euro-U.S. Dollar exchange rate. We had deferred foreign currency losses of $20.3 million and $32.8 million at June 30, 2021 and December 31, 2020, respectively, in Accumulated other comprehensive loss associated with our cross currency swap activity. The periodic interest settlements related to our cross currency swap agreements are classified as operating activities. The cash flows that relate to principal balances are classified as financing activities for the cash flow hedges on intercompany debt and investing activities for the net investment hedges.

In January 2021, one of our cross currency swap agreements which was accounted for as a cash flow hedge matured, resulting in a net cash payment of $14.7 million. The net cash payment is included within financing activities on the Condensed Consolidated Statements of Cash Flows.

Fair value measurements

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Assets and liabilities measured at fair value are classified using the following hierarchy, which is based upon the transparency of inputs to the valuation as of the measurement date:

Level 1:	Valuation is based on observable inputs such as quoted market prices (unadjusted) for identical assets or liabilities in active markets.
Level 2:	Valuation is based on inputs such as quoted market prices for similar assets or liabilities in active markets or other inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.
Level 3:	Valuation is based upon other unobservable inputs that are significant to the fair value measurement.

In making fair value measurements, observable market data must be used when available. When inputs used to measure fair value fall within different levels of the hierarchy, the level within which the fair value measurement is categorized is based on the lowest level input that is significant to the fair value measurement.

Fair value of financial instruments

The following methods were used to estimate the fair values of each class of financial instruments: 

•short-term financial instruments (cash and cash equivalents, accounts and notes receivable, accounts and notes payable and variable-rate debt) — recorded amount approximates fair value because of the short maturity period;

•long-term fixed-rate debt, including current maturities — fair value is based on market quotes available for issuance of debt with similar terms, which are inputs that are classified as Level 2 in the valuation hierarchy defined by the accounting guidance;

•foreign currency contract agreements — fair values are determined through the use of models that consider various assumptions, including time value, yield curves, as well as other relevant economic measures, which are inputs that are classified as Level 2 in the valuation hierarchy defined by the accounting guidance; and

•deferred compensation plan assets (mutual funds, common/collective trusts and cash equivalents for payment of certain non-qualified benefits for retired, terminated and active employees) — fair value of mutual funds and cash equivalents are based on quoted market prices in active markets that are classified as Level 1 in the valuation hierarchy defined by the accounting guidance; fair value of common/collective trusts are valued at net asset value (“NAV”), which is based on the fair value of the underlying securities owned by the fund and divided by the number of shares outstanding.

The recorded amounts and estimated fair values of total debt, excluding unamortized issuance costs and discounts, were as follows:

	June 30, 2021				December 31, 2020
In millions	Recorded Amount		Fair Value		Recorded Amount		Fair Value

Income Tax Disclosure [Abstract]

Income Taxes

Income TaxesWe manage our affairs so that we are centrally managed and controlled in the United Kingdom (“U.K.”) and therefore have our tax residency in the U.K. The provision for income taxes consists of provisions for the U.K. and international income taxes. We operate in an international environment with operations in various locations outside the U.K. Accordingly, the consolidated income tax rate is a composite rate reflecting the earnings in the various locations and the applicable rates.

The effective income tax rate for the six months ended June 30, 2021 was 14.7%, compared to 25.3% for the six months ended June 30, 2020. We continue to actively pursue initiatives to reduce our effective tax rate. The tax rate in any quarter can be affected positively or negatively by adjustments that are required to be reported in the specific quarter of resolution.

The liability for uncertain tax positions was $46.6 million and $46.3 million at June 30, 2021 and December 31, 2020, respectively. We record penalties and interest related to unrecognized tax benefits in Provision for income taxes and Net interest expense, respectively, on the Condensed Consolidated Statements of Operations and Comprehensive Income, which is consistent with our past practices.

Commitments and Contingencies

Commitments and Contingencies

Legal proceedings

We have been, and in the future may be, made parties to a number of actions filed or have been, and in the future may be, given notice of potential claims relating to the conduct of our business, including those relating to commercial, regulatory or contractual disputes with suppliers, authorities, customers or parties to acquisitions and divestitures, intellectual property matters, environmental, asbestos, safety and health matters, product liability, the use or installation of our products, consumer matters, and employment and labor matters.

While we believe that a material impact on our consolidated financial position, results of operations or cash flows from any such future claims or potential claims is unlikely, given the inherent uncertainty of litigation, a remote possibility exists that a future adverse ruling or unfavorable development could result in future charges that could have a material adverse impact. We do and will continue to periodically reexamine our estimates of probable liabilities and any associated expenses and receivables and make appropriate adjustments to such estimates based on experience and developments in litigation. As a result, the current estimates of the potential impact on our consolidated financial position, results of operations and cash flows for the proceedings and claims described in the notes to our consolidated financial statements could change in the future.

Environmental matters

We have been named as defendant, target or a potentially responsible party in a number of environmental clean-ups relating to our current or former business units. Accruals for environmental matters are recorded on a site-by-site basis when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated, based on current law and existing technologies. It can be difficult to estimate reliably the final costs of investigation and remediation due to various factors. In our opinion, the amounts accrued are appropriate based on facts and circumstances as currently known. As of June 30, 2021 and December 31, 2020, our recorded reserves for environmental matters were not material.

Product liability claims

We are subject to various product liability lawsuits and personal injury claims. A substantial number of these lawsuits and claims are insured and accrued for by Penwald, our captive insurance subsidiary. Penwald records a liability for these claims based on actuarial projections of ultimate losses. For all other claims, accruals covering the claims are recorded, on an undiscounted basis, when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated based on existing information. The accruals are adjusted periodically as additional information becomes available. We have not experienced significant unfavorable trends in either the severity or frequency of product liability lawsuits or personal injury claims.

Warranties and guarantees

In connection with our disposition of businesses or product lines, we may agree to indemnify purchasers for various potential liabilities relating to the sold business, such as pre-closing tax, product liability, warranty, environmental, or other obligations. The subject matter, amounts and duration of any such indemnification obligations vary for each type of liability indemnified and may vary widely from transaction to transaction.

Generally, the maximum obligations under such indemnifications are not explicitly stated and as a result, the overall amount of these obligations cannot be reasonably estimated. Historically, we have not made significant payments for these indemnifications. We believe that if we were to incur a loss in any of these matters, the loss would not have a material adverse effect on our financial position, results of operations or cash flows.

We recognize, at the inception of a guarantee, a liability for the fair value of the obligation undertaken in issuing the guarantee. In connection with the disposition of the Valves & Controls business, we agreed to indemnify Emerson Electric Co. for certain pre-closing tax liabilities. We have recorded a liability representing the fair value of our expected future obligation for this matter.

We provide service and warranty policies on our products. Liability under service and warranty policies is based upon a review of historical warranty and service claim experience. Adjustments are made to accruals as claim data and historical experience warrant.

The changes in the carrying amount of service and product warranties of continuing operations for the six months ended June 30, 2021 were as follows:

Beginning balance	$	37.0
Service and product warranty provision	29.9

Stand-by letters of credit, bank guarantees and bonds

In certain situations, Tyco International Ltd., Pentair Ltd.’s former parent company (“Tyco”), guaranteed performance by the flow control business of Pentair Ltd. (“Flow Control”) to third parties or provided financial guarantees for financial commitments of Flow Control. In situations where Flow Control and Tyco were unable to obtain a release from these guarantees in connection with the spin-off of Flow Control from Tyco, we will indemnify Tyco for any losses it suffers as a result of such guarantees.

In the ordinary course of business, we are required to commit to bonds, letters of credit and bank guarantees that require payments to our customers for any non-performance. The outstanding face value of these instruments fluctuates with the value of our projects in process and in our backlog. In addition, we issue financial stand-by letters of credit primarily to secure our performance to third parties under self-insurance programs.

As of June 30, 2021 and December 31, 2020, the outstanding value of bonds, letters of credit and bank guarantees totaled $98.9 million and $99.1 million, respectively.
